Abstract

The invention discloses a high-temperature reaction furnace for producing sodium antimonate by sodium pyroantimonate dehydration, which comprises a furnace body capable of rotating horizontally, a feeder and a tail gas treatment device which are arranged on one side of the furnace body, and an igniter arranged on the other side of the furnace body, wherein the furnace body is arranged on a furnace stage through a roller ring on the periphery, and forms a rolling contact with support rollers on the furnace stage; the inner wall of the furnace body is provided with an inner screw conveyer; and the periphery of the furnace body is provided with a power gear ring which meshes with a driving gear, which is fixed to the furnace stage and connected with a rolling motor. The invention aims to provide a high-temperature reaction furnace for producing sodium antimonate by sodium pyroantimonate dehydration, which shortens the production cycle, implements circulating production and has the advantages of high production efficiency, energy saving, environment friendliness and labor saving.

Description

technical field [0001] The invention belongs to the field of sodium antimonate production equipment, in particular to a high-temperature reaction furnace for producing sodium metaantimonate by dehydrating sodium pyroantimonate. Background technique [0002] Sodium antimonate is divided into sodium pyroantimonate and sodium antimonate, of which sodium antimonate is the dehydration product of sodium pyroantimonate; sodium antimonate, also known as sodium antimonate hydrate, is mainly used as a flame retardant, high-grade glass Clarifying agent, electronics industry, enamel opacifying agent, etc. [0003] Sodium pyroantimonate is an inorganic salt compound of antimony with the chemical formula NaSbO 3 ·3H 2 O, low toxicity, it is produced from antimony products such as antimony oxide through alkali and hydrogen peroxide, and its appearance is white powder. Sodium antimonate has the chemical formula NaSbO 3 , Sodium antimonate is generally generated by sodium antimonate unde...
